Yes, thank you jl2012 for one of the very best and helpful (long-term context providing) threads on this board.
You used to update a graph (as per OP) that, apart from price and regression line, showed the expected price of any day based on the best regression line up to that day. I thought that interesting. If you get the time and inclination, could you perhaps update it again at some point?
TIA
Please see last page. This chart doesn't need to update every day as it makes very small difference
